Executive Summary

CVE-2026-22739 is a vulnerability in Spring Cloud Config Server that occurs when the profile parameter from a request is substituted. If the server is configured to use the native file system as a backend, this substitution can allow unauthorized access to files outside the intended search directories.

Additionally, when the server uses a source control backend, the profile parameter can be injected into the URL pointing to the source control repository, which can enable Server-Side Request Forgery (SSRF) attacks.

Impact Analysis

This vulnerability can lead to unauthorized access to sensitive files outside the configured directories on the Spring Cloud Config Server, potentially exposing confidential information.

In cases where a source control backend is used, it can also enable SSRF attacks, which might allow attackers to make unauthorized requests from the server, potentially leading to further exploitation or data breaches.

The CVSS base score of 8.6 indicates a high severity impact, with high confidentiality impact, low integrity impact, and low availability impact.
